Hi, the bug seems to be fixed by running "sudo update-initramfs -u" and
correcting the BIOS configuration display setting from "Switchable
Graphics" to "Discrete Graphics".
The PulseAudio Daemon message is gone and the radeon UMS message is
gone.
The background of this is i have blacklisted i915 Intel Integrated
Graphics by blacklisting it using "install i915 /bin/true". Thanks for
the attention

Title:
Radeon error, kernel says No UMS support in radeon module
Status in linux package in Ubuntu:
Invalid
Bug description:
A day ago i have edited ~/.config/pulse/client.conf with the following
change:
; autospawn = yes
to
autospawn = no
Today i face Xorg error with the following message:
[drm] VGACON disable radeon kernel modesetting.
[drm:radeon_init [radeon]] *ERROR* No UMS support in radeon module!
If this change caused this error, please advise a better way to solve
another bug "pulseaudio : Daemon already running" if the
~/.config/pulse/client.conf should remain as "; autospawn = yes".
